For almost 100 years, between 360 and 270 bc, Macedonia was one of the world’s most dynamic states. Under the leadership of King Philip II its strength was exerted so as to dominate its Balkan and Greek neighbours. Under his son Alexander III that strength was projected eastwards as far as India. This is a fairly familiar story, especially that of Alexander, whose achievements are still astonishing over 2,000 years later. Though not intentionally so, the work of Philip was fundamental to that of Alexander; the two have to be considered together.
